That people aren't willing to even question how animal suffering has been normalized to the extent it has. I'm not fully vegetarian or vegan even if I'm trying to reduce meat consumption. But I've had this conversation with people and some don't even want to discuss this while eating arguing it ruins their appetite. I think its a great thing that Lab-grown meat could end the suffering of animals in many ways in the future. And people will look back and ask how we could ever do something so awful to animals.
What I think is sad is that for the short foreseeable future animal suffering will still be treated as normality and nothing will change until there is no reason or way it will inconvenience humans in any way to shift away. I find that morally appalling to some regard
Honestly aside from the nutrients the infrastructure around them is crazy. For now lab-grown meat still is very expensive but I think if optimized and produced at mass scale the cost could definitely go below what meat from animal facotries costs
